1、Circuit Breaker (MCCB)

Circuit breaker must be connected between the three-phrase AC power

supply and power input terminals L1, L2, L3 on XT1 so as to cut off the

power when the spindle drive motor is over circuited or short circuited.

MCCB capacity is generally 1.5 to 2 times of the rated motor current, refer to

Table 3.1

MCCB's time characteristics should considerate the drive unit (motor rated

current 1.5 to 2 times, 1 min) and time characteristics.

Each drive unit must be corresponding to a MCCB；when multiple drive unit

share a MCCB, In order to cut off the power supply and prevent the failure

expanding，suggest using the failure chain output relay of drive unit to

control the line magnetic contactor to ensure safety。

2、leakage circuit breaker

When choosing a specific leakage circuit breaker，please select Operating

current of drive unit above 30mA.

When choosing a general leakage circuit breaker，please select Operating

current of drive unit above 200mA,time is above 0.1S。

Installing isolation transformer between a general leakage circuit breaker and

drive unit could effectively avoid the breaker malfunction

3、Line electromagnetic contactor

Line electromagnetic contactor capacity is generally 1.5 to 2 times the rated

motor current selection, please refer to Table 3.1

Frequently using open / closed magnetic contactor will cause heating of the

soft-start resistance, and even burning.

Interval time of open / closed magnetic contactor should be more than 10

minutes

4、 Surge Suppressors

In order to eliminate arc and damage, extend the life of the contactor

connect a three-phase AC interrupter serve on output main contact of electromagnetic

contactor

5、Input AC reactor

In order to protect the rectifier components from damage caused by the high-current's

impacting to the input power circuit, the power input side need to connect to an input

AC reactor and increase its power factor. It can effectively eliminate the influence of

high harmonics, prevent other equipment from damage caused by the voltage wave

changes, and eliminate the unbalanced input current caused by phase voltage

unbalanced.

Input AC reactor capacity is generally 1.5 to 2 times of the rated motor current,

please refer to the Table 3.1.

6、Input filter

In order to reduce a high-frequency interference noise from source line coupling to

drive unit, suggest install matching input filter on the current input of drive unit

Input filter capacity is generally 1.5 to 2 times the rated motor current selection,

please refer to Table 3.1.

Please select the dedicated servo (inverter) input filter。

Input filter should be well grounded

Figure 5-7 Input filter on the current input of drive unit

5.3.4 Control power wiring

HSV-180AS-200，300，450 drive unit must connect AC220Vcontrol power，during

power-on process, you should connect AC220V control power firstly and then

connect the AC380V strong electric power。

5.3.5 Output side wiring of main circuit

1、motor connection

Output terminals U、V、W of drive unit should connected to terminals U、V、W of the

three-phase AC motor according to the correct phase

If A30 motor phase sequence error alarm appears at the first running,

prompt users motor terminal phase sequence error will be wrong, you just

need to exchange V,W

Distance between drive unit and motor wiring should generally be less than

40 m

2、External Braking Resistor

The braking voltage of HSV-180AS spindle drive is DC700 V. For the maximum

braking current, see Table 3.1.

(1)A 70 Ω/500 W braking resistor has been built in HSV-180AS-035，050，

075and a maximum of five times overload is allowed (continuing for one second). An

external braking resistor is required when the drive unit's load or inertia is big. The

braking time is shorter when the load or inertia is bigger, and the resistance value is

smaller and its power is bigger. However, the maximum braking current cannot

exceed the drive's maximum braking current. Generally, the total braking power of

the braking resistor is 10% to 20% of the rated motor power.

Connect P and BK terminals of the spindle drive with the external braking

resistor if an external braking resistor is used. In this case, the internal resistor and the

external resistor are serial connected. Table 5.8 shows the recommended external

braking resistor.

(2) There is no braking resistor built in HSV-180AS-035，050，075,you have to

connect to external braking resistor. The braking time is shorter when the load or

inertia is bigger, and the resistance value is smaller and its power is bigger. However,

the maximum braking current cannot exceed the drive's maximum braking current.

Generally, the total braking power of the braking resistor is 10% to 20% of the rated

motor power.

Connect P and BK terminals of the spindle drive with the external braking

resistor if an external braking resistor is used. In this case, the internal resistor and the

external resistor are serial connected. Table 5.8 shows the recommended external

braking resistor.

2、The COM signal of the XS4 command input/output interface must be

connected to the power ground of the external DC24V power supply.

Otherwise, the spindle drive may work improperly.

3、The Darlington transistor is served as the output transistor which needs

to be connected to a relay or an optical coupler.The external power supply

is provided by users. Make sure that the polarity is not reversed.

Otherwise, it may damage the spindle drive.

4、XS4 command input / output interface of the COM signal must be connected

with the ground signal of external DC24V，otherwise drive unit cannot

work properly.

2、Switch-value Output Interface

1.Two common wiring example，OUT means out point：（ZSP，READY，ALM，

GET，ORN_FIN）。

Figure 5-16 Connections of switch output signal

2.Input mode: NPN. The input switch-value state is determined by the

spindle drive. When the input of isolation optical coupler is conducted,

the input switch -value state is ON. When the input of isolation optical

coupler is turned off, the input switch-value state is OFF

3.It provides open-collector output, with a maximum of 100 mA current and

25 V external power supply voltage. Therefore, the load of the

switch-value output signal must meet the requirements. If the value

exceeds the maximum value or the output terminal is directly connected

to the power supply, it may damage the spindle drive.

4.If the load is an inductance load such as relay, it must be anti-parallel

with the freewheeling diode (FWD) at both ends. The FWD cannot be reversed.

Otherwise, it may damage the spindle drive.

5.The output transistor is Darlington Transistor. When it is conducted,

the voltage drop between the collector and the emitter (Vce) is about 1V,

which cannot meet the requirement of the TTL low level. So it cannot be

directly connected to the TTL.

NOTE:

The output switch-value state is determined by the spindle drive. When

the output of Darlington Transistor is connected, the output switch-value

state is ON. When the output of Darlington Transistor is disconnected,

the output switch-value state is OFF.

The state of the spindle alarm output switch (ALM) is the exception. When

the output of Darlington Transistor is connected, the state of ALM is OFF,

otherwise, it is ON.

3、Z-phase Pulse Open Collector Output Interface

（1）Incremental photoelectric encoder Z signal send to the CNC system by

open collector， meanwhile providing two types of output :Z_OUT(PNP)and

ZPLS_OUT（NPN）

Figure 5-18Z-phase pulse open-collector output interface（PNP）

Figure 5-19Z-phase pulse open-collector output interface（NPN）

（2）Z-phase pulse signal is outputted by the open-collector.，with a

maximum of 100mA current

（3）The Z-phase pulse signal is usually very narrow. Therefore the PC

must use a high-speed optical coupler receiver, such as 6N137.

（4）The output must be non-isolated output (non-insulated).

4、 Pulse Command Input Interface

Figure 5-20 Differential drive mode of the pulse input

Figure 5-21 Single-ended drive mode of the pulse input

It is recommended that you use the differential drive mode (especially

when the cable is too long) which uses AM26LS31, MC3487 drives or RS422

drives.

The single- ended drive mode can reduce the action frequency. You can

determine the value of R according to a 10 to 15 mA drive current and a

maximum of 25V external power supply voltage.

Generally, if the value of VCC is 24 V, the value of R is 1.3 K to 2 K

(VCC = 24 V, R = 1.3 K to 2 K);

If the value of VCC is 12 V, the value of R is 510 Ω to 820 Ω (VCC =

12 V, R = 510 Ω to 820 Ω);

If the value of VCC is 5 V, the value of R is 82 Ω to 120 Ω (VCC = 5

V, R = 82 Ω to 120 Ω).

In the single-ended mode, users provide the external power supply. Make

sure that the polarity is not reversed. Otherwise, it may damage the

spindle drive.

5、 Analog Command Input Interface

Figure 5-22 Differential analog input interface

Figure5-23 Single-ended analog input interface

Figure 5-24 c Differential analog potentiometer input interface

Figure 5-25 d Single-ended analog potentiometer input interface

The analog input interface is differential. According to different

connection methods, it has two forms connection, differential connection

and single-ended connection. The range of input voltage is -10V to +10V.

In the differential connection, the analog ground wire is connected to

the input reference terminal at the side of controller. Therefore, it

needs three wires to connect the controller and drive unit.(see Figure

5-13 a)

In the single-ended connection, the analog ground wire is connected to

the input reference terminal at the side of the drive. Therefore, it needs

two wires to connect the controller and the drive.(see Figure 5-13 b)

The differential connection is superior to the signal-ended connection

for its good anti-common-mode interference characteristic.

The input voltage cannot exceed the range from -10V to +10V. Otherwise

it may damage the spindle drive.

It is recommended that the shield cable be used to reduce the noise

disturbance.

It is normal for the analog input interface has a zero bias which can be

compensated by setting the movement parameter PA-8.

The analog interface is non-isolated.

6、Spindle Motor optic-electrical encoder/Spindle Encoder Output Interface

Figure 5-26 Spindle motor optic-electrical encoder/spindle encoder

output interface

The encoder signal is outputted by the differential drive（AM26LS31）.

The controller input terminal can adopt AM26LS32 receiver and must be

connected to an approximate 330Ω termination resistor.

The controller ground wire and the drive ground wire must be reliably

connected.

The output must be non-isolated output.

The controller input terminal can also adopt an optical coupler receiver.

However, the receiver must be a high-speed optical coupler, such as 6N137.

Grounding

Grounding wire must be thick. The spindle drive and spindle motor must

be connected to PE.

Grounding resistance <4Ω

Use cold pre-insulated terminals to connect terminals and make sure that

the connection is firm.

Install the non-fuse circuit breaker to promptly cut off the external

power when a spindle drive fault occurs.

It is recommended that the power is supplied after passing the input AC

power reactor and input filter to improving the anti-jamming capability.

It is recommended that shield cable be used to prevent other electrical

equipments from interference.

Control signal XS4, feedback signal XS3 for spindle motor

optic-electrical encoder, spindle encoder feedback signal XS2, and XS1

Serial Interface

Diameter

Shield cable is used (stranded shield cable is the best choice), and the

cross-sectional area is greater than or equal to 0.12mm²(AWG24-26). The

shielded layer must be connected to the metal shell of the connection plug.

Cable length

The cable must be short. The length of the control signal cable XS4 is

not greater than 10 meters, and the length of the feedback signal cable

XS2, XS3 is no more than 40 meters.

Wiring

The wiring must be away from the electric power circuit to prevent

interference.

Install surge absorbers with inductive components (coils) of related

circuits. Freewheeling diodes are antiparallel connected to the DC coils,

and RC absorbed circuits are paralleling connected to the AC coils.

3、I/O input/output terminal XS5

（1）Diameter: use ordinary cable or shielded cable, wire cross-sectional area

≥ 1.5mm2.

（2）Cable length: cable length as short as possible and not more than 10

meters.

5.8 Standard Wiring

Caution

U, V, W on XT2 must be connected to the motor windings in

corresponding order and cannot be reversed.

Cables and wires must be fixed and cannot be near the radiator

of the spindle drive or motor. Otherwise, the insulation

properties may be reduced due to overheat.

In the spindle drive, large-capacity of electrolytic capacitor

exists, which leads to the remaining of high voltage even after

power off. Therefore, do not touch the spindle drive or motor

within five minutes after the power off.

Terminals P, BK on XT2 are connected to the external braking

resistor.

Terminal P and BK cannot be shorted. Otherwise it will damage the

spindle drive.

“Shell” in the wiring diagram refers to the mental shell of the

wiring plug. The cable shield must be connected to the metal shell.

First unravel the shield and avoid twisting together. Then loop

part of the shield and cut off the rest. Last cover the looped

shield with casing, and weld the exposed shield to the metal shell.
